Structural Design and Optimization of Fan Blade Repair Robot Based on CFD

摘要: 风场对风机叶片修复机器人高空作业时的稳定性产生直接影响。本文提出了一种面向高空作业的风机叶片修复机器人结构设计方案，并根据风场分析结果对其部分结构进行优化。首先建立了修复机器人的三维结构模型。其次根据高空修复作业环境，结合CFD软件对修复机器人在不同风场下的力学特性进行有限元分析，得出风场对修复机器人吸附稳定性影响较大的区域在吸盘连杆处。最后根据上述分析结果针对修复机器人主体及吸盘进行优化设计和仿真分析。通过对比优化前后的分析结果，可以证实机器人主体及吸盘优化结果的有效性和可靠性，为风机叶片修复机器人设计提供理论依据。

Abstract: The wind field has a direct influence on the stability of fan blade repair robot when working at high altitude. In this paper, a structural design scheme of fan blade repair robot for high-altitude opera-tion is proposed, and some of its structures are optimized according to the wind field analysis re-sults. Firstly, the three-dimensional structure model of the repair robot is established. Secondly, according to the high-altitude repair working environment, the mechanical characteristics of the repair robot under different wind fields were analyzed by finite element method combined with CFD software, and it was concluded that the area where the wind field had a great influence on the adsorption stability of the repair robot was at the connecting rod of the sucker. Finally, according to the above analysis results, the optimization design and simulation analysis are carried out for the main body of the repair robot and the suction cup. By comparing the analysis results before and af-ter optimization, the validity and reliability of the optimization results of the robot body and the suction cup can be verified, and the theoretical basis for the design of the fan blade repair robot can be provided.
